The Zohar, Introduction, Article “Yitro (Jethro)”: The Zohar explains the order of the emanation of the Partzufim of Atzilut: Atik, AA, AVI, and ZA, how the source of everything, the Masach of Malchut of Midat ha Din, uses Partzuf Atik, operates in AA to conceal the Hochma there… Afterwards, it explains VAK de ZA concerning six curtains, and the embroidered curtain, GAR de ZA.
The authors of The Book of Zohar revealed the order of relationships between them and inside the connection among each other they revealed Partzufim, worlds, qualities, and inner discernments. All of this is present between a person and others.
When a person sees others as connected together, it is called “the World of Infinity.” If he sees them as connected partially, it is called Partzufim that are above him. That is how they speak to each other, revealing every quality and calling it “Rabbi Yossi, Rabbi Hiya, Rabbi Elazar, Rabbi Shimon,” as well as various pictures of nature.
All of these are states that our souls go through in the process of their correction. I know from my personal experience how difficult it is for a person to depict a very simple picture in his imagination: that there is nothing besides the separated souls. Their total division is perceived by them as our world. Their partial unification, the inclusion of the desires into one another by the principle “Love your neighbor as yourself” creates the sensation of the Upper World in the souls.
Their total unity is perceived by the souls as the World of Infinity: unbounded, unlimited unity, and accordingly, total fulfillment by Light.
